Autocar UK test drives a BMW i8 prototype.

The new BMW i8 goes on sale next year and it’s rumored to be priced at around 100,000 euros.

Pairing an exceptionally lightweight, aerodynamically optimized body with cutting-edge BMW eDrive technology, a compact, turbocharged 1.5-liter BMW TwinPower Turbo gasoline engine and intelligent energy management, the BMW i8 marks the next stage in the evolution of the Efficient Dynamics strategy.

BMW i8 Prototype   First Drive

It can operate solely on electric power, which means no tailpipe emissions, and offers the dynamic performance of a sports car, with an expected 0 – 60 mph sprint time under 4.5 seconds.

Here is an excerpt from the review:

I drove the i8 on BMW’s Miramas test track in France. On the infield handling course and surrounding roads, it immediately dispelled any lingering doubts about its ability to deliver truly engaging driving traits. It is extremely agile, with somewhat light but extremely direct electro-mechanical steering. You can sense the low centre of gravity in the way the futuristic looking coupé enthusiastically turns in to corners. Its dynamic properties are characterised by an inherent responsiveness, nimbleness and light-footedness to the handling, which immediately stands out as one of the new car’s strengths.

There is very little body movement as lateral forces rise, although its ability to carry serious speed through corners is limited by the current state of chassis tune, which clearly favours understeer – something it tended to do quite early on the freshly laid bitumen of the BMW test track. It’s nothing too troubling, mind. But when the rest of the car is so well sorted, the deficiency in front-end bite tends to be magnified, and it quickly had the DSC (dynamic stability control) working as we began to push the i8 hard through corners.

BMW’s engineering team says the understeer is partly down to the characteristics of the specially developed Bridgestone Potenza tyres. They boast relatively soft side walls and are engineered to deliver low rolling resistance for maximum efficiency, even with the optional rubber. Still, this is an engineering mule, not a pre-production prototype, and predictably BMW says there are developments in the pipeline that will provide the definitive production version of the i8 with greater mid-corner purchase than the example we sampled.

The good news – no, the great news – is that you can dial back the threshold of the DSC and rely on it’s the prodigious torque developed by the front electric motor and combustion engine to kick out the tail in low-to-medium-speed corners, allowing you to straighten the line when conditions permit. So it is progressive, but there’s also a good deal of adjustability in the chassis as well.

    A NO FUEL ENGINE, powered by atmospheric heat is now on its way to
    prototype. This was first suggested by Jacob Wainwright in 1903. His 20
    years of dissent from The Second Law of Thermodynamics was ignored.
    After studying the Wainwright papers, the inventor was inspired to
    create a practical NO FUEL ENGINE.

    The inventor has demonstrated that The Second Law of Thermodynamics does not
    universally apply to heat engines. This engine is much simpler than one
    he patented earlier proving that fact. See NO FUEL ENGINE at http://www.aesopinstitute.org.
    (Note the Proell Effect Abstract from the American Institute of
    Physics). There is also a link to a free google book of the Wainwright
    papers on that site.

    These engines have the potential to replace
    most
    diesel generators. One kilowatt engines are being designed both as
    emergency generators and as an on-board recharge for electric cars.
    However, they may not provide as much power as the BMW engine.

    Once engines that need no fuel are validated by an independent lab, and
    desktop versions are available, a perpetual commotion could open paths
    to other surprising energy alternatives.

      Aesop Institute is a wonderfully elaborate fraud, operated by Mark Goldes.

      Mark Goldes, starting in the mid-seventies, engaged for several years in the pretense that his company SunWind Ltd was developing a nearly production-ready, road-worthy, wind-powered “windmobile,” based on the windmobile invented by James Amick; and that therefore SunWind would be a wonderful investment opportunity.

      After SunWind “dried up” in 1983, Goldes embarked on the long-running pretense that his company Room Temperature Superconductors Inc was developing room-temperature superconductors; and that therefore Room Temperature Superconductors Inc would be a wonderful investment opportunity. He continues the pretense that the company developed something useful, even to this day.

      And then Goldes embarked on the pretense that his company Magnetic Power Inc was developing “NO FUEL ENGINES” based on “Virtual Photon Flux;” and then, on the pretense that MPI was developing horn-powered “NO FUEL ENGINES” based on the resonance of magnetized tuning-rods; and then, on the pretense that his company Chava Energy was developing water-fueled engines based on “collapsing hydrogen orbitals;” and then, on the pretense that he was developing ambient-heat-powered “NO FUEL ENGINES.” Goldes has even claimed that Jacob T. Wainwright already patented an ambient-heat-powered engine 100 years ago – even though Wainwright himself certainly never made any such claim, at all. Wainwright’s only patent for a turbine or engine was not for any ambient-heat-powered engine, but for a pressurized-gaseous-fluid-powered engine. The innovation of the patent was the use of water to reduce speed – not any use of ambient heat.

      Goldes’ forty-year career of “revolutionary invention” pretense has nothing to do with science, but only with pseudoscience and pseudophysics – his lifelong stock-in-trade.

        The post above is a troll attack. It contains a number of half-truths and outright lies.

        SunWind Ltd. provided the electric drive system and invented the Trade Name windmobile. The Amick invention was originally a racing land yacht. We were only involved in the prototype and never claimed
        it was production ready. It was the cover story for Popular Science in November of 1976 and SunWind is mentioned in the article.

        Magnetic Power Inc. (MPI) and its subsidiary, Room Temperature Superconductors Inc. were awarded four Small Business Innovation Research Contracts by the Department of Defense. These included a
        Phase II award by the USAF after successful tests of our room temperature superconductors by the Air Force during the Phase I contract. Since these are polymer materials we created the name Ultraconductors™. Almost 1,000 samples of these remarkable materials were independently reproduced for the USAF by Fractal
        Systems. The White House Office of Science and Technology Policy assisted with this program. Funding was interrupted by global economic factors beyond our control. Development is expected to resume under the auspices of CHAVA Energy.

        Magnetic Power Inc. (MPI) was formed to explore the potential of ambient energy powered magnetic systems to generate electricity. A magnetic generator was demonstrated in Germany in 1925 and by 1937 was producing 6,000 watts. It became a Top Secret program for the Nazi Navy which wanted to use it to recharge submarine batteries without requiring a sub to surface. The lab was bombed late in World War II. British Intelligence published a Report in 1946 indicating the work was genuine. That Report was declassified in 1979. See The
        Coler Papers at http://www.chavascience.com for more of the story. MPI Magnetic Generators are still under development under the auspices of CHAVA Energy. See http://www.chavaenergy.com

        As anyone reading the introductory material at http://www.aesopinstitute.org can readily see I do not (and have never) claimed that Jacob Wainwright patented an engine powered by ambient heat. Only that he
        delivered scientific papers claiming it was possible. The inventor of the
        patent pending NO FUEL ENGINE on that website was inspired by the Wainwright papers. The false statement reveals this troll does not seem to understand the English language very well.

    Mark Goldes’ latest adventure in flimflam is to declare that a “FUEL-FREE TURBINE invented by a Russian scientist runs on atmospheric pressure.”

    But when we read the patent application, we find that actually the turbine does NOT run on atmospheric pressure – it requires compressed air. This is clearly indicated even in the article by Kondrashov posted by Goldes on his flimflam website. Kondrashov says:

    “To create a sample of such an engine, you can use ready-made devices, such as a load-bearing element – a low-power turbine module turboshaft turbine engine, and to compress the air… any type of compressor…”

    Kondrashov filed his patent application in 2003. No patent was awarded.

    Mark Goldes assures us in his note prefacing Kondrashov’s article that “We understand the science behind this jet engine.” But since he incorrectly describes it as an engine powered by “atmospheric pressure” – which it certainly is not – in fact he shows that he doesn’t even understand that the engine requires a supply of compressed air in order to spin at all.

    Although Kondrashov does pretend in some of his statements that the turbine will be powered by “atmospheric pressure,” in fact it is evident from his application that the proposed turbine is made to spin only by the use of compressed air.

    In his patent application, Kondrashov states:

    “To set the above engine in operation, it is necessary to create pressure of working medium (e.g. air) in pneumatic accumulator 18. The compressed air is fed through check valve 19 and/or 20.”

    Thus, Kondrashov indicates that an external compressor must be used to fill the turbine’s compressed air tank before the turbine can be started. But he tries to pretend that once the turbine starts to spin, there will be no further reliance on the external compressor – the spinning turbine itself will compress the air that is making the turbine spin. So despite his own false description of the turbine as making use of “low-grade atmospheric energy,” what Kondrashov actually presents in his patent application is a perpetual motion machine in the form of a self-powered air compressor. This is probably the reason why no patent was awarded. It is exactly analogous to trying to use a generator to power a motor to spin the generator to power the motor to spin the generator. It doesn’t work.

    The Second Law of Thermodynamics rules out strictly ambient heat engines.

    Expecting an ambient heat engine to do any work, with only one heat reservoir, is exactly equivalent to expecting a teapot to boil water by absorbing heat from a block of ice.

    Both processes are ruled out by the very same law – the Second Law of Thermodynamics.

    “It is impossible for any device operating on a cycle to produce net work from a single temperature reservoir; the production of net work requires flow of heat from a higher temperature reservoir to a colder reservoir.”

    In a strictly ambient heat engine there are not two heat reservoirs at different temperatures; no reservoir would be available at any temperature other than the ambient temperature. Therefore the engine would have to DECREASE the total entropy – and therefore we know for certain that the engine will disappoint us. It will never be able to do any work.

    Flow of heat from a block of ice to lukewarm water would also result in a DECREASE of the total entropy.

    Once again: Expecting an ambient heat engine to do any work, with only one heat reservoir, is exactly equivalent to expecting a teapot to boil water by absorbing heat from a block of ice. Anyone who claims to be developing a “prototype” of such an engine is only developing a pretense, and nothing more.

    Max Planck, in his “Treatise On Thermodynamics,” explains how the Second Law of Thermodynamics “may be deduced from a single simple law of experience about which there is no doubt.” Here is the “single simple law of experience” he proposes:

    “It is impossible to construct an engine which will work in a complete cycle, and produce no effect except the raising of a weight and the cooling of a heat-reservoir.”

    This “law of experience” is very similar to a principle suggested by William Thomson (Lord Kelvin):

    “It is impossible, by means of inanimate material agency, to derive mechanical effect from any portion of matter by cooling it below the temperature of the coldest of the surrounding objects.”

    The “simple law of experience” offered by Planck is therefore commonly known as the “Kelvin-Planck statement” of the Second Law of Thermodynamics. But we see from Planck’s “Treatise” that Planck himself did not quite regard it as a statement of the Second Law, but rather as a “starting point” or postulate from which the Second Law may be deduced.

    Here is Planck’s rendition of the Second Law itself:

    “The second law of thermodynamics states that there exists in nature for each system of bodies a quantity, which by all changes of the system either remains constant (in reversible processes) or increases in value (in irreversible processes). This quantity is called, following Clausius, the entropy of the system.”

  • Kelfin Planck

    In Mark Goldes’ patent application for his ludicrous “POWERGENIE” horn-powered tuning-rod engine, he described the tuning-rod as “an energy transfer and multiplier element.”

    But of course, for the tuning-rod to “multiply” energy, it would need to disprove the law of conservation of energy.

    Goldes’ use of the term “energy multiplier element” reflected his pretense that the “revolutionary breakthrough” of the amazing “POWERGENIE” could disprove the law of conservation of energy, by presenting the world with a working “energy multiplier.”

    Goldes even claimed in 2008 that the POWERGENIE had been demonstrated already in an electric car, driven 4800 miles by his energy-multiplying horn-powered tuning-rod.

    But it seems that most people, for some reason, had difficulty accepting the notion that the law of conservation of energy could be proven false.

    And Goldes no doubt noticed that the Second Law of Thermodynamics – that “the entropy of an isolated system tends to increase with time and can never decrease” – is much less clear to most people than the conservation of energy.

    So now, after leaving aside the pretense that he could somehow “multiply energy” with a magnetized tuning-rod, Goldes has chosen to focus, instead, on the pretense that he can disprove the Second Law with an engine powered only by ambient heat.

    There is no “new science” in any of Goldes’ “revolutionary breakthroughs.” There is only pseudoscience and pretense – and nothing new, at all.
